| Abstract: | We succeeded in providing for the first time the evidence of the NanoBud structure (fullerenes attached to the surface of SWCNT) by Raman spectroscopy in combination with TEM. This work was performed on the individual freestanding NanoBud structure. The Raman features corresponding to the typical vibrational modes of fullerenes were observed in the range of 1440-1480 cm(-1). The simultaneous presence of SWCNT and fullerene features in the Raman spectrum is in good agreement with the TEM and ED investigations on the same NanoBud structure, which confirmed the Raman measurement interpretation of the SWCNT chirality assignment (16,11) and the presence of fullerenes on the surface of the SWCNT. |
